Summary

Emlog CMS <= 2.6.14 contains a stored cross-site scripting (XSS) vulnerability in the article publishing module (/admin/article.php). A remote authenticated attacker can inject arbitrary JavaScript code via the article content. When an administrator reviews or previews the submitted article in the backend, the malicious script executes in the admin's browser session, allowing the attacker to perform administrative actions such as creating a backdoor administrator account.

Risk Assessment

An attacker can hijack the admin session and perform administrative actions, such as creating a backdoor admin account, leading to full system compromise.

Recommendation

It is recommended to update Emlog CMS to a version above 2.6.14 and implement input validation and sanitization in the article publishing module.
